[Installation precautions]
Contents Countermeasures (Reference)
When installed
near adjacent
houses
Perform installation work so that operating
sound does not disturb the neighbors.
1) Install a soundproof barrier
2) Change the installation site
When there is
the possibility
of strong wind
1) If the outdoor unit is exposed to strong
wind, capacity may drop, frost may form
during heating, and operation may be
stopped by high pressure rise. In addition,
when a very strong wind blows, the fan
may be damaged.
2) When a very strong wind blows, there is
the possibility of the outdoor unit being
toppled over if held only by foundation
bolts
1) Install with the outlet side
keep a sufficient distance
away from a facing wall or
fence.
2) Make the outlet direction
and wind direction
perpendicular.
3) Fasten the outdoor unit
using toppling prevention
hardware (procured at the
site).
When snow
accumulates
If the outdoor unit is covered by accumulated
snow, it may not be able to operate.
1) Make the foundation as
high as possible.
2) Perform snow prevention
work.
